Dentist Guide is a leading source for finding dentists of all specialties. There are many kinds of dentists, the most common being a general dental practice which includes most examination, diagnosis, treatment planning, treatment, and prevention of disease. The dentist and with the aide of other dental employees such as a dental hygienist frequently use X-rays and other equipment to ensure correct diagnosis and treatment planning. Treatment may include filling dental cavities, removing the nerves of teeth (R.C.T or Root Canal Treatment), treating diseases of the gums, removing teeth (Extraction), and replacing lost teeth with bridges and dentures (Dental Plates). Anesthesia is often used in any treatment that might cause pain. Teeth may be filled with Gold, Silver, Amalgam, or Cements, and with fused Porcelain Inlays. Dentists treat diseases of the mouth and gums such as trench mouth and Periodontitis. The most important part of general dental practice is preventive dentistry. If a dentist examines a patient's teeth at regular intervals, a disease may be detected and treated before it becomes serious. Dentists also demonstrate proper methods of brushing and flossing the teeth. They may advise their patients about what food to eat or to avoid for good dental health. Dentists may also treat teeth with Fluorides or other substances to prevent decay.

Other dental specialties include:

Dental Public Health (study of dental epidemiology and social health policies)

Endodontics (root canal therapy)

Oral and Maxillofacial Pathology (study, diagnosis, and often the treatment of oral and maxillofacial related diseases)
